often if needed. Measure only in fully occupied rooms. Reading should be less than 700 PPM plus
outside air CO2 PPM.
700 PPM + 350 PPM = 1050 PPM
Assume outside CO2 is 350 if temperature is below 41 degrees and air is not stagnant with no- wind.
Record all occupied space CO2 levels on forms provided. Provide the outdoor CO2 level as well as
the high and low CO2 extremes below:

9. Other
a. Paint
No peeling and/or flaking paint found.
If planned building renovation will damage paint or if peeling paint is discovered, lead testing may be
necessary. If peeling paint is found, send email to the building Principal and the Facilities Director
alerting them of the problem. Staff and teachers need to pick up any flakes of paint to prevent
children from being exposed. The Facilities Director will advise the Facilities Coordinator (a Certified
Lead Paint Renovator) to test the paint for lead. Lead paint was discontinued in 1978. Buildings built
after 1978 are exempt from lead paint testing.
If lead is present, required repairs should be done immediately using lead-safe methods and, if
necessary, a licensed lead contractor.
Location(s) of known peeling paint in building:
b. The following preventive measures are being taken to reduce lead exposure.
i. Play areas and toys are cleaned nightly.
ii.
